Abstract: An aqueous anti-microbial disinfectant solution for contact lenses contains an effective amount of an active ingredient which is an anti-microbial, organosilicon quaternary ammonium salt chemically bonded to a water soluble, high molecular weight organic polymer. The solution is non-toxic and non-irritating to the eye, and does not adsorb or penetrate into a contact lens.

Abstract: The toxic effects of platinum compounds used in chemotherapy can be negated by the use of a selenium-containing compound. A new selenium-containing platinum compound has been found to be useful as a so-called platinum compound type anti-cancer medicine which can self-detoxify platinum toxicity.

Abstract: An improved and novel animal litter is described utilizing alumina, aluminosilicates or coal residues as the substrate intimately mixed with monomers containing acid functionalities which are polymerized in-situ. The resulting mixture is then extruded into pellets of any size or shape. Animal litter pellets prepared by this invention have vastly improved water adsorption properties, deodorizing capacity, and they do not have to be cured at high temperatures.

Abstract: An anti-microbial composition is provided comprising an aqueous solution of an oxyhalogen compound and a polymeric germicide. The oxyhalogen compound is preferably stabilized chlorine dioxide and the polymeric germicide is preferably a quaternary ammonium compound such as a copolymer of at least one difunctional tertiary amine and a dihalo organic compound such as 1,4-dihalo-2-butene, a copolymer of at least one difunctional tertiary amine, at least one monofunctional tertiary amine and a dihalo organic compound such as 1,4-dihalo-2-butene, or a polyguanide such as hydrochloride salt of poly(hexamethylene biguanide). The anti-microbial composition thus formed is used for the treatment of soft contact lenses to disinfect the same with an optimum effect while minimizing the irritant possibilities thereof and also minimizing absorption of the composition into the porous and hydrophilic surfaces of soft contact lenses such that there is a minimal release of absorbed substances after treatment.

Abstract: The invention relates to a fertilizer composition which comprises coal ash, and a relatively water insoluble polymer capable of gradually decomposing to slowly release nitrogen polymerized uniformly on said coal ash. The polymer is formed by the in situ polymerization of an aldehyde and a polymerizable organic nitrogen containing compound capable of reacting with two or more equivalents of said aldehyde in the presence of an acid. The coal can be fly ash, bottom ash or boiler slag and can be derived from anthracite, bituminous or subbituminous coal or from lignite coal. The acid can be phosphoric acid, the aldehyde formaldehyde and the polymerizable organic nitrogen containing compound urea.

Abstract: A method of preparing a snow and ice control composition to improve traction on ice and snow covered surfaces. The composition comprises coal ash, binder, a melting depressant and enough water to form a dough-like mixture with said mixture pelletized by extrusion through a die and cured to form particles ranging in size from 1/16 th to 11/2 inches. The resulting said pellets have excellent strength and can be formulated to be environmentally acceptable.

Abstract: There is disclosed a battery with a separator of ethylene-vinyl alcohol copolymer. Inert filler and plasticizer can be used. The separator can be used in acid or alkaline electrolyte.

Abstract: Water insoluble, hydrophilic copolymers of 50 to 98% of hydroxyalkyl acrylate or methacrylate wherein the alkyl group has 2 to 3 carbon atoms with 2 to 50% stearyl acrylate or methacrylate are prepared. They are particularly effective for sealing and coating building materials.

Abstract: Fly ash, bottom ash and/or boiler slag are used as animal litters and particularly as cat litters. These materials exhibit remarkable absorbent and deodorizing capabilities and their low cost makes them a commercially more attractive substitute for Fuller's earth and other currently available cat litter compositions. These materials are also effective when used in admixture with Fuller's earth or other known cat litters.

Abstract: N-chloro chloroalkanamides or chloro hydrocarbyl substituted alkanamides of the formula ##STR1## where R.sub.1 is hydrogen or alkyl of 1 to 6 carbon atoms, R.sub.4 is alkylene or chloroalkylene of 1 to 5 carbon atoms, n is 0 or 1, R.sub.2 and R.sub.3 are hydrogen, chlorine, alkyl of 1 to 4 carbon atoms, alkaryl of up to 8 carbon atoms or aryl of up to 8 carbon atoms, have been found useful as herbicides. Preferably n is 0 and R.sub.2 and R.sub.3 are hydrogen chlorine, phenyl or alkyl or 1 to 2 carbon atoms. Most preferably R.sub.2 and R.sub.3 are hydrogen or chlorine.

Abstract: Plasticized solid, water-insoluble, water-swellable, hydrophilic polymers having the recurring unit ##STR1## wherein R is a divalent aliphatic hydrocarbon radical of 2 to 8 carbon atoms; where R' is hydrogen or alkyl of 1 to 4 carbon atoms; preferably hydrogen or methyl; wherein R" is hydrogen or alkyl of 1 to 12 carbon atoms; and wherein n is an integer of at least 1; and as the plasticizer therefor, preferably a liquid compound characterized by amino and hydroxyl groups, said compound having a relatively low vapor pressure.

Abstract: An animal litter is prepared comprising a loose substrate treated with a solid water soluble copolymer of (a) 5 - 35% of a hydroxyester of a 2-alkenoate having the formula ##STR1## wherein R is alkylene of 2 to 4 carbon atoms and R' is hydrogen or alkyl of 1 to 4 carbon atoms, n is an integer and (b) a copolymerizable water soluble monomer or polymer. The polymer is prepared in solution in a solvent or one of the monomers. A fragrance is also added.

Abstract: Novel halogenated triazines which are useful as insecticides, especially as herbicides.
